Mercedes-Benz E300 vs BMW 530d

What's the difference?

The E-Class is stacked with kit, looks great, and is an effective and comfortable way to get around in built-up areas or across the countryside.

While it’s not the most dynamically engaging - it’s pipped by its Bavarian rival there - it offers more comfort-oriented features than most, and the cabin is a pleasant place to spend a day driving.

If you're disposed towards stumping up the asking price, the extra outlay for the 'Plus Package' will probably be most relevant to you if you’re covering long distances due to the Airmatic suspension.

Otherwise, even a simple-spec E300 provides a step up from what you might expect from an executive sedan.

Not all superheroes wear capes, and we're proud to report the 530e does its bit for green motoring without feeling the need to shout about it. And with no price or specification penalty, it's easier being green than ever before, and the pricing of this BMW really puts the cat amongst the canaries.

Evolution rather than revolution is obvious when it comes to the E-Class’ styling, but that’s in Mercedes’ best interests, because it’s still a good-looking thing, and being a bit subtle is warranted in the executive sedan game.

The biggest changes come in the headlights and tail-lights. Up-front there are now more than one million pixels in the LED headlights, which have adaptive high beam as standard and are more connected to the grille via black trim, as has been seen in EQ electric models.

Underneath, the bumper now features an AMG-style 'A-wing' apron as part of the 'AMG Line' exterior package as standard. A set of 20-inch AMG alloys are also included.

To the rear, and the digital tail-lights feature a Mercedes-Benz star motif, making its lighting signature now more recognisable from behind.

The German Rainbow is well-represented with mostly shades of grey, black, or white available, though 'Verde Silver Metallic' is a slightly retro green, and 'Nautic Blue Metallic' is a subtle and classy tone.

The daring ‘Manufaktur’ shade of 'Patagonia Red Metallic' is a $2500 option, as is 'Opalite White Bright' while 'Alpine Grey Solid' is $2900.

Crucially, there's nothing weird about the way the 530e looks. While some green cars look like they've been designed by one of the kids from 3rd Rock from the Sun, the 530e looks much the same as the rest of the range, save a few tiny but telltale giveaways - like the e-drive badging outside, and what looks like a bonus fuel flap tucked in behind a front wheel that houses the whole plug-in bit.

And we really, really like it. It's elegant and statesman-like from every angle, and looked especially important in the deep-blue colour of our test vehicle. It's not over-designed, with body creases used sparingly, and the occasional glint of polished silver that rings the windows and the grille adds a final sense of shininess to an understated design. 

Inside, there's more going on than you might normally find in a BMW. The hugely complicated digital display screen now includes everything from battery charge, power usage to the usual assortment of speedometers and petrol readouts. 

It doesn't feel overdone or crazily festooned, but there's more at play here than in your usual BMW.

The dash is busy, too, with a wide screen emerging from a centre stack that also houses a CD player and a digital aircon setup, which in turn sits above a complex centre console from which you can alter driving settings, control the multimedia or cycle through electric modes. It doesn't feel overdone or crazily festooned, but there's more at play here than in your usual BMW.

Elsewhere inside, the seats are beautifully designed, with a quilted leather highlight through the middle, while the gloss-black strip that lines the dash hides a dual strip of ambient interior lights that also runs across all four doors.

Inside, the E-Class should feel familiar to anyone who’s spent time in a recent Benz, though the Superscreen might be the main point of difference. It’s an immediately comfortable place, though, with a relatively visually busy cabin.

The seats and their adjustability mean most drivers and passengers, regardless of height and size, should feel supported (and ideally relaxed), while touch-points are mostly either leather upholstery or digital screens.

The steering wheel, also seen in plenty of other Mercedes models, is a bit of a let-down, however, with its haptic touch pads on a slightly busy two-tier layout. This millennial found it irritating, surely too will the usually older E-Class buyer.

There are a few other small annoyances, one being that the MBUX Assistant sometimes won’t hear a command, or that not everything seems to be able to be controlled by it. The climate control vent positions are electrically adjustable to certain pre-sets through the menu, but the MBUX Assistant isn’t able to do this for you.

And while the driver display and central multimedia screen are fairly user-friendly, it’s not always immediately apparent what the quickest way to find some information or a setting is.

Our test car was fitted with the 'Plus Package', which means four-zone climate control available to the rear seats, which my 180cm-tall self found spacious with plenty of headroom, kneeroom, and even a fair bit of room under the driver’s seat.

Behind the rear seats, there’s a generous 540 litres of boot space, exactly the same capacity as the previous generation E-Class.

As the world's motoring tastes shrink faster than a lap-banded Clive Palmer, it's easy to forget the joys of the full-size sedan, but the space for passengers and luggage in the 5 Series will have you questioning your downsizing ways.

Upfront, there's plenty of room between front-seat riders, who will also share two smallish cup holders, along with room in each front door for bottles. There's also a dedicated wireless charge pad (which, because of its tight design, is crazy difficult to actually remove your phone from), but you'll also get two USB points and a power outlet that's hidden in the sizeable centre storage bin as standard fit.

Backseat riders get heaps of space, both in width and in leg room behind the front seats. And there's twin air-con temp controls and twin power outlets, too. But middle-seat passengers will be forced to sit with their legs on either side of the raised tunnel, which will definitely impact on comfort.

The boot's still sizeable, despite shrinking slightly to house the battery/fuel tank setup

Best to ditch the fifth passenger, then, and deploy the pull-down seat divider, which also houses two cup holders. Finally, there are three ISOFIX attachment points, one for each seat in the back.

The boot's still sizeable, despite shrinking slightly to house the battery/fuel tank setup (the tank has been moved further back to accomodate the batteries), and can be adjusted to be a flat load area if you'd like, offering up to 410 litres with the rear seats in place.

The 530e commands a 530i-equalling $108,900 price tag, which is genuinely impressive when you consider all the extra bits and pieces that go into make a plug-in hybrid. That money buys you a well-equipped car, and only those allergic to money need reach for the options list.

As standard, you'll find leather-wrapped - and heated in the front - sports seats, 19-inch alloy wheels and a 10.25-inch touchscreen that pairs with a really very good 16-speaker Haman Kardon stereo. Wireless Apple CarPlay is available, but it'll cost you an extra $500. To be honest, though, we didn't miss it.

You'll also find adaptive LED headlights, a huge head-up display (so big, in fact, that it impedes vision when climbing steep hills), dynamic dampers, an auto opening/closing boot and a self-parking system, along with BMW's suite of self-driving tech - but we'll come back to that under the Safety sub-heading.

This lone E-Class variant is powered by a turbocharged 2.0-litre engine pumping out 190kW and 400Nm, assisted by a 48-volt battery system. Under EQ boost, an extra 17kW and 205Nm is available for a short time.

It’s hooked up to a nine-speed auto that drives the rear wheels, and it’s all pretty traditional… for 2024, that is.

Mercedes says the E300 is able to hit 100km/h in a respectable 6.3 seconds.

Drift around in pure EV mode and you'll be relying on the 530e's 83kW and 250Nm electric motor, which will provide what BMW refers to as "between 28 and 32 real-world kilometres".

Run out of range, or simply use too much throttle, and the 2.0-litre petrol engine comes into play, adding 135kW and 320Nm to the mix. All up, that's 185kW and 420Nm - respectable numbers by any measure, and enough to match the petrol-powered 530i's zero to 100km/h sprint of 6.2 seconds.

That power is fed through an eight-speed automatic transmission before being sent exclusively to the rear wheels, where it belongs.

Mercedes claims the E-Class drinks 7.2L/100km on the combined cycle, and though we weren’t able to test that properly at the pump on the launch program, the trip computer showed up to 9.4L/100km after some quite spirited driving, which gradually averaged out to about 8.6L/100km in the afternoon once some more calm, E-Class-appropriate distance had been covered.

With its 50L fuel tank, the E-Class should theoretically be able to cover 694km on a single tank if the 7.2L/100km is achieved, though realistically it would be much less, 550-600km depending on driving style.

Like a Facebook relationship status, it's complicated. The 530e will sip a claimed combined 2.3 litres per hundred kilometres on the claimed/combined cycle, which is amazing for a car this size. Better still, it seems genuinely achievable - at the vehicle's launch, our own Richard Berry recorded a stunning 2.0 litres per hundred kilometres on a short test route.

But that's with a full load of battery charge on board. For our week with the 530e we were unable to actually plug it in (living in Sydney, I can't afford a garage), so once the initial battery charge had been used we were back to mostly petrol power. Unlike some other plug-in hybrids we've driven, we found it very difficult to recharge the battery to any meaningful level using regenerative braking, so once we were flat we stayed flat. If we had plugged it in, it would have been a two-hour recharge using a specialised wall unit, or about four hours using a normal plug.

As a result, though, our fuel use was closer to 7.0 litres per hundred kilometres after some considerable real-world testing.

While the E-Class has taken fairly sizeable steps in terms of its tech, it remains a fairly traditional car from behind the wheel, save for a few small changes like its mild-hybrid system and rear-wheel steering.

It’s still a petrol-powered rear-drive sedan, and it feels built more for eating up highway kilometres than it does tackling twisty turns. But that’s okay, because it will still do the latter.

Comfort is the main focus, clearly, for the E300, and the big Merc does it well. We weren’t offered a car without Airmatic air suspension on the launch, but the E-Class doesn’t seem like it would be particularly rough without it.

With it, however, large bumps and minor road annoyances only make their way into the cabin in the sense that you’re aware of them, but not bothered by them.

That slight dulling of feedback does extend to the steering wheel however, where, despite the rear-wheel steering making the car more nimble, the feedback to the driver is less encouraging of eager driving. 

While 190kW on paper doesn’t seem like enough, the E-Class makes do with its meagre engine quite well - and even though it can seem like it’s working a bit too hard at times, the E-Class’ natural state isn’t responding to a planted foot, so it’s unlikely to be a daily bother.

Engine noise, as well as wind and road noise are suitably dulled by the E300’s NVH fitout, too.

The tuning of its drive modes, in particular Comfort and Sport, seemed well-judged on our drive loop, with the option to set the 'Individual' mode to a custom configuration, most elements in Comfort while the drivetrain is set to Sport is particularly helpful when on gentle, high-speed country roads.

If you do start to approach the limits of the big sedan’s capability, it’ll let you know fairly early on. The heavy E-Class isn’t prone to sudden lurching or poor handling, and isn’t much phased by mid-corner bumps.

It’s not as dynamically engaging as some rivals, particularly the 5 Series, but it does appear to be a better provider of cross-country comfort.

There's so much to like about the way the 530e sets about saving the world, and that's mostly because it doesn't shout about it, either to the driver or the outside world.

It's very much an underpants inside its pants superhero, which makes us like it even more. Set off in EV mode, and the 530e will drift silently away from the curb, burning battery power over fuel for as many as 30(ish) kilometres. But equally important, the shift from green to gas is largely imperceptible, with the petrol engine joining in willingly when you ask it to - usual via a prod of your right foot.

It is so effortlessly smooth that you need to really pay attention to notice the eight-speed 'box changing gears at city speeds, and it's commendably quiet, whichever drive mode you're in.

Downsides? Well, it doesn't feel quite as sharp as it's conventional-engined siblings. The batteries add around 230kg in weight, which never helps, and it all feels a little softer and a little less dynamic, even with Sport mode engaged. BMW assures us the adaptive suspension setup and tune is identical, but the 530e feels noticeably softer when you tackle a twisting back road. And that encourages you to use your right foot a little more, which in turn negates the whole electric thing in the first place.

One of the great joys of BMWs has always been their ability to transform from cosseting comfort to rear-drive rocket when you want them to, and you can't help but notice the 530e isn't quite up to that challenge. But if your intentions are mostly city- and freeway-based, then this plug-in BMW is almost indiscernible from its petrol-powered sibling.

You'll want for little here, with front, front-side and full curtain airbags joining parking sensors, a surround-view camera and a self-parking system.

You can also expect active cruise control, lane control assist with lane keep assist (so it will stay between the lane markings for you), AEB and cross-traffic warning. And all of that means that, technically, the 530e can drive for you. That is, of course, if you don't mind driving like a dick - in full-autonomous mode it will swerve from lane marking to lane marking like it's playing bumper bowling.

The E-Class comes with Mercedes’ fairly industry standard five-year, unlimited kilometre warranty, though Mercedes-Benz Australia was unable to confirm exact servicing pricing on the launch. 

It does however list pricing for the E-Class on its website for a three-service pack at $3325, four at $4535, and five at $6800, the latter averaging out to $1360 each.

This could increase with the new generation car, and Mercedes doesn’t list estimated serving pricing for new E-Classes yet in its booking system (I checked with one of the test cars).

Servicing intervals are every 12 months or 25,000km, whichever comes first.

Like the rest of the 5 Series range, the 530e falls under BMW's three-year, unlimited-kilometre warranty. There are no set service intervals, either, with BMW using what it calls 'condition-based' servicing. In other words, the car will tell you when it requires a trip to the service centre.

The batteries are covered by a separate warranty covering six years or 100,000km.
